Misformed characters
● If characters are improperly formed, producing hollow images, the
paper stock may be too slick. Try a different paper. See “Printer
paper specifications.”
● If characters are improperly formed, producing a wavy effect, the
laser scanner may need service. Verify that characters are
improperly formed on a self-test page. If so, contact an HP-
authorized dealer or service representative. See “Service and
support.”
